NOTE: If you don’t see the cache-clearing option, you’re probably running an older version of the app that doesn’t include that feature. The version number of your installed copy of the app is shown at the bottom of Periscope for iOS’s settings interface.

To check how much storage space the Periscope app itself and its stored data are taking up on your device, go to Settings → General → Storage & iCloud Usage, tap Manage Storage below the Storage heading, then choose Periscope from the list.

From there, you can also delete Periscope by tapping Delete App.
